Answer to Question 1

ANSWER: Hundreds of thousands of people live on gravelly alluvial fans in Los Angeles, Palm Springs, Phoenix, Tucson, Salt Lake City, Denver, and elsewhere. Most of these fans were built up from fast-moving slurries of sand, gravel, and boulders (debris flows). Even arid regions can have periods of intense or prolonged rainfall. People who live on such fans are at considerable risk from debris flows.
